ABSTRACT

An idler adjustment assembly includes a support block; a first set of one or more adjustment components to move a first wear component between a first plurality of positions that are adjacent to an external surface of a first side of the support block; a second set of one or more adjustment components to move a second wear component between a second plurality of positions that are adjacent to an external surface of a second side of the support block; a first set of one or more alignment components to maintain a first alignment of the first wear component relative to the external surface of the first side of the support block; and a second set of one or more alignment components to maintain a second alignment of the second wear component relative to the external surface of the second side of the support block.

TECHNICAL FIELD

The present disclosure relates generally to a track system for atrack-type machine and, for example, to an idler adjustment assembly ofthe track system.

BACKGROUND

Track-type machines, for example dozers, excavators, and skid-steerloaders, are commonly used in applications where traction is critical orlow ground pressure is important. Such a machine may include a framethat supports an internal combustion engine, and left and right tracksthat transfer power from the engine to a ground surface. Each of thetracks typically includes an idler (also referred to as an idler wheel).

The idler is a rolling element that passively rolls against an innerside of the track and is configured to engage with other components ofthe track to facilitate operation of the track (e.g., to enable movementof the machine along the ground surface). Depending on a level of theground surface and/or a work application of the machine, the idler mayneed to be adjusted (e.g., a position of the idler within the track mayneed to be adjusted) to ensure that the track smoothly rolls (e.g., withminimal bounce) across the ground surface (e.g., by causing “an impactregion” of the track to impact the ground surface at an angle within aparticular angle range). Furthermore, from time to time, over a coursemachine operation, the idler and the other components of the trackundergo wear and the idler may therefore need to be readjusted.Adjusting (and readjusting) the idler can be a time-consuming andlabor-intensive task that is prone to error (e.g., the idler may not beadjusted to an optimal position within the track), which can affect aperformance and an operable life of the idler, the other components ofthe track, the track, and the machine.

U.S. Pat. No. 7,237,631 (the '631 patent) discloses a vertical idleradjuster that includes at least one removable spacer to adjust avertical position of an idler shaft relative to a roller frame of atrack type machine. While the '631 patent discloses some benefits, theidler adjustment assembly of the present disclosure does not require useof removable spacers.

The idler adjustment assembly of the present disclosure solves one ormore of the problems set forth above and/or other problems in the art.

For example, as shown in FIG. 2 , the support block 200may include a holding component 202 (e.g., a hole, a recess, or anothercomponent) that is configured to hold an end of the idler shaft of theidler 114. While FIG. 2 , shows the holding component 202 as positionedat a particular end of the support block 200, the holding component maybe positioned anywhere on the support block 200 (e.g., in the middle ofthe support block 200 or at another end of the support block 200).

The support block 200 may be a metal block (e.g., a cast metal block).At least a part of the support block 200 may have a C-shapedcross-section (e.g., as shown in FIGS. 3C-3D) that enables access (e.g.,by a tool, such as a wrench) to an internal portion 204 of the supportblock 200 (e.g., the support block 200 may be “dished out” to provideaccess to the internal portion 204 of the support block 200).Accordingly, as further shown in FIG. 2 , the support block 200 mayinclude a first side 206 (e.g., a top side), a second side 208 (e.g., abottom side), and a third side 210 (e.g., a back side).

The idleradjustment assembly 116 may include the support block 200, a first wearcomponent 302, a second wear component 304, a first set of one or moreadjustment components 306, a second set of one or more adjustmentcomponents 308, a first set of one or more alignment components 310, anda second set of one or more alignment components 312. The first wearcomponent 302 may include a first set of one or more connectionsubcomponents 314 and/or a first set of one or more alignmentsubcomponents 316, and the second wear component 304 may include asecond set of one or more connection subcomponents 318 and/or a secondset of one or more alignment subcomponents 320.

FIGS. 3A-3B show a first cross-sectional view of the idler adjustmentassembly 116 (e.g., along a line associated with line A of the supportblock 200 shown in FIG. 2 ). FIGS. 3C-3D show a second cross-sectionalview of the idler adjustment assembly 116 (e.g., along a line associatedwith line B of the support block 200 shown in FIG. 2 ). Relativepositions of the components of the idler adjustment assembly 116 (e.g.,to each other) are the same, or similar, as shown in FIGS. 3A and 3C,and relative positions of the components of the idler adjustmentassembly 116 (e.g., to each other) are the same, or similar, as shown inFIGS. 3B and 3D.

Each of the first wear component 302 and second wear component 304 maybe a wear shoe, a wear block, or a similar component that comprises ametal material, a rubber material, a rubber/metal composite material, ora similar material. Each of the first wear component 302 and second wearcomponent 304 may be configured to contact an idler frame (not shown) ofthe idler system 112 (e.g., the idler frame may be configured to holdthe idler 114 and the idler adjustment assembly 116 within the tracksystem 102). Accordingly, each of the first wear component 302 andsecond wear component 304 may be configured to maintain (e.g., bycontacting the idler frame) a particular position of the idler 114and/or the idler adjustment assembly 116 within the track system 102(e.g., a particular vertical position within the track system 102).

The first wear component 302 may be configured to be adjacent to anexternal surface of the first side 206 of the support block 200. Forexample, as shown in FIGS. 3A-3D, the first wear component 302 may beconfigured to be disposed above the external surface of the first side206 of the support block 200. As further described herein, the firstwear component 302 may be configured to be moved, by the first set ofone or more adjustment components 306, between a first plurality ofpositions that are adjacent to the external surface of the first side206 of the support block 200 (e.g., between a plurality of positionsthat are disposed above the external surface of the first side 206 ofthe support block 200). For example, as shown in FIGS. 3A and 3C, thefirst wear component 302 may be positioned at a first position, of thefirst plurality of positions, such that the first wear component 302contacts the external surface of the first side 206 of the support block200, and, as shown in FIGS. 3B and 3D, the first wear component 302 maybe positioned at a second position, of the first plurality of positions,such that the first wear component 302 does not contact the externalsurface of the first side 206 of the support block 200.

In some implementations, each position of the first plurality ofpositions may be a different distance from the external surface of thefirst side 206 of the support block 200. Accordingly, the first wearcomponent 302 may be positioned at a particular position, of the firstplurality of positions, such that the first wear component 302 is aparticular distance from the external surface of the first side 206 ofthe support block 200, wherein the particular distance satisfies (e.g.,is greater than or equal to) a distance threshold. The distancethreshold may be greater than or equal to, for example, 10 millimeters(mm), 25 mm, or 50 mm.

The second wear component 304 may be configured to be adjacent to anexternal surface of the second side 208 of the support block 200. Forexample, as shown in FIGS. 3A-3B, the second wear component 304 may beconfigured to be disposed below the external surface of the second side208 of the support block 200. As further described herein, the secondwear component 304 may be configured to be moved, by the second set ofone or more adjustment components 308, between a second plurality ofpositions that are adjacent to the external surface of the second side208 of the support block 200 (e.g., between a plurality of positionsthat are disposed below the external surface of the second side 208 ofthe support block 200). For example, as shown in FIGS. 3A and 3C, thesecond wear component 304 may be positioned at a first position, of thesecond plurality of positions, such that the second wear component 304contacts the external surface of the second side 208 of the supportblock 200, and, as shown in FIGS. 3B and 3D, the second wear component304 may be positioned at a second position, of the second plurality ofpositions, such that the second wear component 304 does not contact theexternal surface of the second side 208 of the support block 200.

In some implementations, each position of the second plurality ofpositions may be a different distance from the external surface of thesecond side 208 of the support block 200. Accordingly, the second wearcomponent 304 may be positioned at a particular position, of the secondplurality of positions, such that the second wear component 304 is aparticular distance from the external surface of the second side 208 ofthe support block 200, wherein the particular distance satisfies (e.g.,is greater than or equal to) a distance threshold. The distancethreshold may be greater than or equal to, for example, 10 mm, 25 mm, or50 mm.

Additionally, or alternatively, the first wear component 302, whenpositioned at a first position, of the first plurality of positions, maybe a first distance from the external surface of the first side 206 ofthe support block 200, and the second wear component 304, whenpositioned at a second position, of the second plurality of positions,may be a second distance from the external surface of the second side208 of the support block 200. The first distance may be the same as thesecond distance (e.g., the first distance may equal the seconddistance), or the first distance may be different than the seconddistance (e.g., the first distance may not equal the second distance).

The first set of one or more adjustment components 306 may be configuredto move the first wear component 302 between the first plurality ofpositions that are adjacent to the external surface of the first side206 of the support block 200. For example, as shown in FIGS. 3A-3D, thefirst set of one or more adjustment components 306 may be configured tomove the first wear component 302 along a first axis (e.g., ay-axis) ofthe idler adjustment assembly 116. The second set of one or moreadjustment components 308 may be configured to move the second wearcomponent 304 between the second plurality of positions that areadjacent to the external surface of the second side 208 of the supportblock 200. For example, as shown in FIGS. 3A-3D, the second set of oneor more adjustment components 308 may be configured to move the secondwear component 304 along the first axis of the idler adjustment assembly116. The first axis may be orthogonal to the external surface of thefirst side 206 of the support block 200 and/or to the external surfaceof the second side 208 of the support block 200.

Each adjustment component 306, of the first set of one or moreadjustment components 306, may be an adjustment fastener. Accordingly,each adjustment component 306 may be configured to be disposed within acorresponding bore 212, of the first set of one or more bores 212, ofthe first side 206 of the support block 200 and to be connected to acorresponding connection subcomponent 314, of the first set of one ormore connection subcomponents 314, of the first wear component 302. Forexample, as shown in FIGS. 3A-3D, each adjustment component 306 may be athreaded fastener that includes a first end configured to connect to thecorresponding connection subcomponent 314, a threaded shank configuredto be disposed within and engage with the corresponding bore 212, and asecond end configured to extend into the internal portion 204 of thesupport block 200. The corresponding connection subcomponent 314 mayinclude a nut (e.g., a lock nut), a washer (e.g., a lock washer), and/ora similar structure configured to maintain a connection of theadjustment component 306 to the first wear component 302. Thecorresponding bore 212 may be a threaded bore (e.g., a bore thatincludes a threaded insert, a threaded bushing, and/or a similarstructure) configured to engage with the threaded shank of theadjustment component 306. The second end of the adjustment component 306may include an engagement head (e.g., a hexagonal head or a similarstructure) that is configured to engage with a tool (e.g., a wrench).

Accordingly, an operator of the machine 100 may use the tool to rotatethe adjustment component 306 (e.g., counterclockwise or clockwise alonga rotation axis of the adjustment component 306) and thereby cause thefirst wear component 302 (or a portion of the first wear component 302associated with the corresponding connection subcomponent 314) to movealong the first axis of the idler adjustment assembly 116 (e.g., up ordown, along the y-axis). In this way, the operator may use the tool toengage with each of the first set of one or more adjustment components306 to cause the first wear component 302 to move between the firstplurality of positions that are adjacent to the external surface of thefirst side 206 of the support block 200 (e.g., as shown in FIGS. 3A-3D).

Each adjustment component 308, of the second set of one or moreadjustment components 308, may be an adjustment fastener. Accordingly,each adjustment component 308 may be configured to be disposed within acorresponding bore 214, of the second set of one or more bores 214, ofthe second side 208 of the support block 200 and to be connected to acorresponding connection subcomponent 318, of the second set of one ormore connection subcomponents 318, of the second wear component 304. Forexample, as shown in FIGS. 3A-3D, each adjustment component 308 may be athreaded fastener that includes a first end configured to connect to thecorresponding connection subcomponent 318, a threaded shank configuredto be disposed within and engage with the corresponding bore 214, and asecond end configured to extend into the internal portion 204 of thesupport block 200. The corresponding connection subcomponent 318 mayinclude a nut (e.g., a lock nut), a washer (e.g., a lock washer), and/ora similar structure configured to maintain a connection of theadjustment component 308 to the second wear component 304. Thecorresponding bore 214 may be a threaded bore (e.g., a bore thatincludes a threaded insert, a threaded bushing, and/or a similarstructure) configured to engage with the threaded shank of theadjustment component 308. The second end of the adjustment component 308may include an engagement head (e.g., a hexagonal head or a similarstructure) that is configured to engage with a tool (e.g., a wrench).

Accordingly, an operator of the machine 100 may use the tool to rotatethe adjustment component 308 (e.g., counterclockwise or clockwise alonga rotation axis of the adjustment component 308) and thereby cause thesecond wear component 304 (or a portion of the second wear component 304associated with the corresponding connection subcomponent 318) to movealong the first axis of the idler adjustment assembly 116 (e.g., up ordown, along they-axis). In this way, the operator may use the tool toengage with each of the second set of one or more adjustment components308 to cause the second wear component 304 to move between the secondplurality of positions that are adjacent to the external surface of thesecond side 208 of the support block 200 (e.g., as shown in FIGS.3A-3D).

In some implementations, the first wear component 302 may be configuredto have a first alignment relative to the external surface of the firstside 206 of the support block 200. For example, each of a top side ofthe first wear component 302 and the external side of the first side 206may have a rectangular shape (e.g., from a top-down point of view).Accordingly, the first wear component 302 may have the first alignmentrelative to the external side of the first side 206 (e.g., when thefirst wear component 302 is adjacent to the external surface of thefirst side 206) such that the edges of top side of the first wearcomponent 302 are respectively parallel with corresponding edges of theexternal surface of the first side 206.

The first set of one or more alignment components 310 may be configuredto maintain the first alignment of the first wear component 302 relativeto the external surface of the first side 206 of the support block 200.For example, the first set of one or more alignment components 310 maybe configured to resist movement of the first wear component 302 along asecond axis (e.g., an x-axis) and/or a third axis (e.g., a z-axis) ofthe idler adjustment assembly 116 (e.g., where the second axis and thethird axis are orthogonal to the first axis of the idler adjustmentassembly 116). That is, the first set of one or more alignmentcomponents 310 may be configured to allow movement of the first wearcomponent 302 along the first axis (e.g., the y-axis) of the idleradjustment assembly 116, but not in any other direction. In this way,with respect to the example above, the first set of one or morealignment components 310 may be configured to maintain the firstalignment of the first wear component 302 such that the edges of topside of the first wear component 302 remain respectively parallel withcorresponding edges of the external surface of the first side 206.

In some implementations, each alignment component 310, of the first setof one or more alignment components 310, may be part of the externalsurface of the first side 206 of the support block 200. For example,each alignment component 310 may be integrated into the external surfaceof the first side 206 (e.g., as a protrusion or a similar structure) andmay be configured to engage with a corresponding alignment subcomponent316 (e.g., a depression or a similar structure), of the first set of oneor more alignment subcomponents 316, of the first wear component 302.Alternatively, each alignment component 310, of the first set of one ormore alignment components 310, may be a dowel, a peg, or a similarstructure. For example, each alignment component 310 may be a dowel,that fits into, and engages with, both an alignment feature 216 (e.g., adepression or a similar structure), of the first set of one or morealignment features 216 of the external surface of the first side 206,and a corresponding alignment subcomponent 316 (e.g., a depression or asimilar structure), of the first set of one or more alignmentsubcomponents 316, of the first wear component 302.

In some implementations, the second wear component 304 may be configuredto have a second alignment relative to the external surface of thesecond side 208 of the support block 200. For example, each of a bottomside of the second wear component 304 and the external side of thesecond side 208 may have a rectangular shape (e.g., from a bottom-uppoint of view). Accordingly, the second wear component 304 may have thesecond alignment relative to the external side of the second side 208(e.g., when the second wear component 304 is adjacent to the externalsurface of the second side 208) such that the edges of the bottom sideof the second wear component 304 are respectively parallel withcorresponding edges of the external surface of the second side 208.

The second set of one or more alignment components 312 may be configuredto maintain the second alignment of the second wear component 304relative to the external surface of the second side 208 of the supportblock 200. For example, the second set of one or more alignmentcomponents 312 may be configured to resist movement of the second wearcomponent 304 along the second axis (e.g., the x-axis) and/or the thirdaxis (e.g., the z-axis) of the idler adjustment assembly 116. That is,the second set of one or more alignment components 312 may be configuredto allow movement of the second wear component 304 along the first axis(e.g., the y-axis) of the idler adjustment assembly 116, but not in anyother direction. In this way, with respect to the example above, thesecond set of one or more alignment components 312 may be configured tomaintain the second alignment of the second wear component 304, suchthat the edges of the bottom side of the second wear component 304remain respectively parallel with corresponding edges of the externalsurface of the second side 208.

In some implementations, each alignment component 312, of the second setof one or more alignment components 310, may be part of the externalsurface of the second side 208 of the support block 200. For example,each alignment component 312 may be integrated into the external surfaceof the second side 208 (e.g., as a protrusion or a similar structure)and may be configured to engage with a corresponding alignmentsubcomponent 320 (e.g., a depression or a similar structure), of thesecond set of one or more alignment subcomponents 320, of the secondwear component 304. Alternatively, each alignment component 312, of thesecond set of one or more alignment components 312, may be a dowel, apeg, or a similar structure. For example, each alignment component 312may fit into, and engage with, both an alignment feature 218 (e.g., adepression or a similar structure), of the second set of one or morealignment features 218 of the external surface of the second side 208,and a corresponding alignment subcomponent 320 (e.g., a depression or asimilar structure), of the second set of one or more alignmentsubcomponents 320, of the second wear component 304.

As indicated above, FIGS. 3A-3D are provided as an example. Otherexamples may differ from what is described in connection with FIGS.3A-3D.

INDUSTRIAL APPLICABILITY

The disclosed idler adjustment assembly may be used in any track-typemachine that utilizes a track system with an idler. In many cases, anidler needs to be adjusted (e.g., a position of the idler within a tracksystem needs to be adjusted), such as to facilitate smooth operation ofthe track system across a ground surface and/or to account for wear ofthe idler and/or other components of the track system. Typically, ahuman operator performs a time-consuming and labor-intensive process toattempt to adjust the idler. For example, the human operator loosensfastener components associated with the idler and an idler adjuster(e.g., that includes a frame and at least one wear component);determines a particular distance that the idler is to be adjusted;identifies, based on the particular distance, a particular number ofshims, one or more springs of a particular length, or other blockmaterial to insert between the frame and the at least one wearcomponent; inserts the particular number of shims, the one or moresprings of the particular length, or the other block material betweenthe frame and the at least one wear component; and tightens the fastenercomponents associated with the idler and the idler adjuster. However,this process can be inaccurate (e.g., the idler may not be adjusted bythe particular distance), such as based on a limited availability ofshims of particular thicknesses, springs of particular length, and/or ofblock material of a particular thickness. For example, the humanoperator may only be able to adjust the idler by discrete distanceincrements, and therefore may adjust the idler to a non-optimal position(e.g., may adjust the idler too much or too little) within the tracksystem.

This can affect a performance and/or an operable life of the idler, theidler adjuster, the track system, and/or the track-type machine. Forexample, an incorrectly adjusted idler has a higher likelihood ofcausing “an impact region” of the track system to impact the groundsurface at a non-optimal angle, which causes the track system to rollnon-smoothly (e.g., with more than an optimal amount of bounce) acrossthe ground surface. This increases an amount of stress and/or wearexerted on the idler, the idler adjuster, the track system, and/or thetrack-type machine over time, thereby affecting longevity andperformance.

The idler adjustment assembly described herein includes a support block,a first wear component, a second wear component, a first set of one ormore adjustment components configured to move the first wear componentbetween a first plurality of positions that are adjacent to an externalsurface of a first side of the support block, and a second set of one ormore adjustment components configured to move the second wear componentbetween a second plurality of positions that are adjacent to an externalsurface of a second side of the support block. Accordingly, to adjustthe first wear component, a human operator engages (e.g., using a tool,such as a wrench) the first set of one or more adjustment components,and to adjust the second wear component, the human operator engages thesecond set of one or more adjustment components. In this way, the humanoperator is able to adjust an idler (e.g., that is associated with theidler adjustment assembly) by moving at least one of the first set ofone or more adjustment components or the second set of one or moreadjustment components. No other shims, springs, and/or block materialare needed to adjust the idler.

Further, the human operator is able to move the first wear component andthe second wear component by any amount (e.g., not just discrete,incremental amounts), thereby increasing a likelihood that the idler isadjusted to an optimal position within a track system of a track-typemachine. This improves a performance and/or an operable life of theidler, the idler adjustment assembly, the track system, and/or thetrack-type machine (e.g., as compared to using a typical idleradjuster). For example, a correctly adjusted idler has a higherlikelihood of causing the impact region of the track system to impactthe ground surface at an optimal angle, which causes the track system toroll smoothly (e.g., with minimal bounce) across a ground surface.Therefore an amount of stress and/or wear exerted on the idler, theidler adjustment assembly, the track system, and/or the track-typemachine is reduced over time, thereby improving longevity andperformance.
